WIPO Patent Application WO/2022/227177
Kind Code:
A1
Abstract:
A connection structure for achieving accurate positioning of a multi-limb concrete-filled steel tube spatial structure and a bearing platform, and a construction method therefor. By providing supporting steel tube units (2), a steel body base unit (3), an anchoring steel unit (4), connecting steel tubes (5) and a concrete poured block (6) on the concrete bearing platform (1), the multi-limb concrete-filled steel tube structure can be relatively used for long-term high-strength support. The present application has the following advantages: first, the multi-limb concrete-filled steel tube structure has strong integrity, a strong internal connection structure, and is not prone to having breakage and disintegration occur after long-term high-load support; secondly, multi-limb steel tubes are uniformly and symmetrically arranged, and the whole connection strength is strengthened by means of the connecting steel tubes, so as to ensure that the whole support structure is uniformly stressed and stable in terms of support; and thirdly, the construction method for the entire multi-limb concrete-filled steel tube structure uses welding and pouring techniques, and the overall structure layout is rational, thereby finally ensuring that the construction operation is simple and efficient.
